many CPU cycles as it checked for data availability, known as check pointing. By using automated database-management tools, the company identified the code responsible for the excess consumption. The company then used additional tools to change the level of check pointing, thereby lowering CPU utilization without rewriting the application code. Optimizing mainframe MIPS consumption, more work can be squeezed out of fewer MIPS to accommodate new applications in support of business growth. The correct approach to capacitymanagement planning will project what savings will mean for the business. It can identify when you need to upgrade and what you need to buy to service the business at the lowest cost. still assuring low-priority workloads get the necessary resources. A proactive approach to performance management can flag a potential problem before it develops and avoid delays that could hurt the business.

Automated IT-management technologies enable mainframe IT teams to identify, prioritize and fix the sources of inefficiency in customer transactions.

Prepare for Growth

Capacity-management planning is critical to know when you must buy additional hardware and predict future requirements without buying too much. Do you have an accurate model to estimate the effect of an increase in business and how it will impact your systems? How do you know you’ll have enough resources to handle an increase in business? In an effort to make data centers more efficient, many businesses move their enterprise applications from distributed servers to the mainframe. They consolidate these applications in virtualized environments running on Linux* on System z*. This move creates a challenge. The mainframe technicians must ensure performance across environments that include Linux objects, in addition to the traditional LPARs and subsystems. Effective capacity-management planning can improve the success of consolidation and virtualization projects. Consider leveraging smart technology with predictive analytics, modeling and other sophisticated features that facilitate right-sizing the mainframe to help meet changing business requirements. These tools ensure mainframe performance is optimized for any changes being made to the environment, such as deploying virtualized applications or adding specialty workload-processing engines, such as IFLs.

Maximize Performance Management

Sharpen Your Disaster-Recovery Approach

Mainframe availability is critical to business success and requires performancemanagement solutions that maximize the availability and performance of mainframe systems on a day-to-day basis. Otherwise, you’re failing to get the full value from your hardware investment. More importantly, these solutions detect systemperformance issues quickly enough to prevent business disruption. Performance management helps you get the most out of your technology investments by managing business-critical applications and ensuring you can provide the service your customers expect—all while protecting your bottom line. If you’re an online retailer, for example, you must have enough cycles to handle customer orders at peak times of the day, every day—not just during the holiday rush. You must determine how to juggle existing resources to give purchase transactions the highest priority, so your Web site performs as expected and customers don’t get frustrated and leave your company’s site before mak ing purchases. A performance-management solution can do real-time resource reapportionment for you, ensuring workloads impacting the bottom line get first priority, while

Disaster recovery (DR) is always a priority for IT due to the costs of data loss—in time, money, reputation and lost business. When faced with environmental growth, mergers and acquisitions, or just rapid change in the infrastructure, DR planning becomes even more complex and is often delayed. Even if funding is cut due to economic reasons, there’s an excellent opportunity to review and update your DR program to be ready when growth resumes. DR includes tactics such as providing remote data centers. Businesses should be able to switch processing to remote centers in the event of an emergency. It’s critical to be confident your DR program will work. Capacity-planning models can be used to test DR plans. This enables you to model the transfer of critical production work to DR systems and determine how well they’ll run. Such a model can show what will happen if you don’t have sufficient capacity. It also helps evaluate the risk and plan enough capacity to properly handle DR. Preventing small problems from becoming major business disasters is important. For example, a common source of failures is a bad SQL change made by a database administrator. Even if the outage is localized, it may result in the loss of
